The BBC3 controller, Danny Cohen, has unveiled plans to turn the channel into the UK's "most ambitious multiplatform network" with all its programmes to be simulcast on the internet.

The digital youth channel is also undergoing a major rebranding as it approaches its fifth anniversary with a pink logo replacing its current blue design and talking animated blobs.

Cohen is hoping BBC3 will become the corporation's first non-rolling news channel to transform from a linear service to a fully multiplatform venture.

He has pledged to put interactive ideas at the heart of the channel's schedule, with regular peak time slots given to user-generated content and viewers encouraged to upload clips of themselves introducing their favourite BBC3 programmes, with the best to be shown on screen.

Unveiling the changes, which will kick off next month, Cohen said today: "BBC3 is aiming to become Britain's most ambitious multiplatform network - combining television and the web into a single, integrated offering.

"At BBC3 we should be known for pioneering risk, and be obsessed with all things new - new talent, new programmes and a new relationship between television and the internet.

"The thinking behind this rebrand of the channel is that we have, in effect, created a BBC3 world in which our content can move seamlessly between TV, online and mobile.

"We have a fantastic lineup of programmes and we are going to make them available wherever young people want them."

Cohen, the former E4 controller who was appointed in April last year, said there would be a particular focus on drama in the new BBC3 winter and spring 2008 schedule.

Six drama pilots will include Phoo Action, written by Tank Girl creator Jamie Hewlett; thriller The Things I Haven't Told You; Being Human, a tale of a vampire, a ghost and a werewolf who share a house; and Mrs In-Betweeny, created by Shameless writer Paul Abbott and Caleb Ranson.

One of the dramas will be chosen to become a series for next year.

The channel will also screen US drama Greek, as well as first run episodes of the second series of Heroes.

Entertainment will be spearheaded by Lily Allen and Friends, based around social networking, and interactive comedy-entertainment show The Wall.

New entertainment format Upstaged will be a mixture of talent show, stamina and social networking, which Cohen has described as "risky".

In comedy, the multi award-winning Gavin and Stacey returns for a second series, while The Wrong Door is a sketch show with CGI.

News bulletin 60 Seconds gets a revamp with the launch of nightly world news update, offering coverage of global events seen through the eyes of news stations around the world.

There will also be a weekly commitment to environmental news and special bulletins on everything from technology to entertainment and weekend sport.

In factual, Pramface Mansion will look at the demands of being a single parent, while Making the Clothes I Wear will see six fans of high street fashion gain first-hand experience of working in the clothing industry in the developing world.

Jack's Story is billed as "intimate look" at the lives of young men fighting in Afghanistan, while a season of one-off documentaries, Lost Innocence, will probe young people's obsessions, including choosing a career in modelling and teen pregnancy.

Find Me the Face will see model scouts competing to find a new star in just one month, while Filthy Gorgeous is billed as the world's first "make-under" show, scrubbing down over-the-top boys and girls to reveal their natural beauty.
